Model ID Cheatsheet

Model ID Cheatsheet is an open-source MCP (Model Context Protocol) server that provides AI assistants and agents with instant, reliable access to a comprehensive, auto-updated registry of 107 current and deprecated AI models across 19 providers. It helps prevent the use of outdated or hallucinated API model names by always providing accurate model IDs, specs, and pricing with sub-millisecond response times. Designed for developers, AI tool builders, and autonomous agents that require up-to-date LLM model metadata for API calls and integration, it plugs directly into platforms like Claude Code, Cursor, Windsurf, Codex CLI, OpenCode, and any other MCP client.
